How To Use Diamond Tool To Reduce Steel In Micro Machining?

The diamond tool is commonly used in micro-machining as it can withstand the micro hardening of the workpiece surface in the course of micro-machining. This micro-hardening creates sufficient resistance to break the tool bit effortlessly in micro milling, but not a diamond tool. Micro-machining making use of diamond tool could be performed at higher speeds and typically fine speeds to produce excellent surface finish such as mirror surfaces and higher dimensional accuracy in non-ferrous alloys and abrasive non-metallic components.

Nevertheless, if a diamond tool were to be utilized to reduce steel, a single of the most widespread engineering materials employed in industries, the diamond tool will face severe tool put on. While diamond only softens at 1350 degree Celsius and melts at 3027 degree Celsius, and is also the hardest material in the planet, it has a weakness. Diamond succumbs to graphitization, which indicates that it will modify its crystal structure to graphite crystal structure at 200 degree Celsius in the presence of a catalyst metal such as carbon steel and alloys with titanium, nickel and cobalt.

There have been various attempts to enhance the tool life of the diamond tool even though cutting steel so as to boost the efficiency and profitability of this operation. Such processes incorporate micro-cutting the steel workpiece in a carbon-rich gas chamber as properly as a cryongenically cooled chamber. However, these techniques demand costly equipment modification and restrict direct supervision of the micro-cutting procedure.

The newest breakthrough came when the diamond tool was subject to ultrasonic vibration throughout micro-cutting. It has been shown that a diamond tool topic to ultrasonic vibration can cut the steel well enough to generate a mirror surface finish with acceptable tool life. The ultrasonic vibration at the diamond tool tip permits the tool face to cool down considerably in the course of the cutting method and delays the chemical reaction between the diamond tool and the steel workpiece. As a outcome, the diamond tool life is elevated by a few hundred occasions.

For example, a single crystal diamond tool with feedrate 5 micron/revolution, cutting speed zero to 5m/min and depth of reduce 10 micron was attached to a ultrasonic vibration generator so that the diamond tool tip vibrated about four microns whilst it was utilised to reduce stainless steel. The mirror surface finish of the reduce steel surface was measured at eight nm Ra!

With far more and much more machining companies moving into the niche micro machining field, such ultrasonic vibration assisted cutting can only aid the progressive organization to attain procedure leadership and innovative differentiation..
